Shocker Lube Only?

so. i hit my nearest pro shop today. after a disapointing day on sunday with my shocker. i had MAJOR fsdo. if i shoot in a 15 second interval, my first shot merely rolled out of the barrel. yea. it was cold.. but stilL! my dwell was high... my input wasnt low either. i tried it all. i lubed up the gun well too. Then, i washed off some lube and added a lighter coat to c if tht helped... but it all failed...

but today at the pro shop, my gun worked fine!???
so im puzzled. then one of the guys there recommended some other kind of gun oil. motion potion. he says tht dnt thicken up like shocker lube and its good to use. so. has smart parts been fooling us the whole time? is shocker grease only rule just a scam?
